Development of Lab Scale Membrane Process for CO2 Capture Using Polymeric Membranes

In order to apply membrane process to the CCS processes, permeation and separation characteristics of each membrane should be evaluated with appropriate working conditions and rigorous regulations. 0.2 Nm³/hr and 1.0 Nm³/hr scale test equipments and 0.2 Nm³/hr multi stage modules were built at KIER combustion-gas processing complex laboratory building. Those test equipments can control temperature, pressure, flow rate, steam amount, gas composition, stage cut, and also real flue gas from 10MW_th scale CFB(circulating fluidized bed) boiler can be supplied. In this study, hollow fiber type membranes and their multi stage configurations were developed for establishing standardization of membrane processes for CCS and certificating membrane performance such as permeance, selectivity, chemical-physical resistance and long term operability.
